A user may locate a cursor at an end of the reference marker and click to register the position. An electronic distance, e.g., a number of pixels between the ends of the reference marker, is normalized to the length of the reference marker. A user selects points on the image on a display to define a line segment on a dimension of interest to be determined. Calculations relate the length of the line segment to the length of the reference marker. A number indicated the desired dimension may be displayed on the image.
